Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Summary of Significant Accounting Policies	Nature of Operations and Summary of Significant Accounting Policies Nature of operations: Westbury Bancorp, Inc. (the Company) is a Maryland savings and loan holding company headquartered in West Bend, Wisconsin and provides a variety of financial services to individuals and small businesses throughout Southeastern Wisconsin. The Company owns 100% of the stock of Westbury Bank (the Bank). The Bank's primary deposit products are checking, savings, money market and term certificate accounts and its primary lending products are consumer, commercial and residential mortgage loans. The Bank is subject to competition from other financial institutions and non-financial institutions providing financial products. Additionally, the Company and the Bank are subject to the regulations of certain regulatory agencies and undergo periodic examination by those regulatory agencies. Organization and principles of consolidation: The consolidated financial statements include the accounts of the Company and the Bank. The financial statements of the Bank include the accounts of its wholly-owned subsidiary, CRH, Inc., a Wisconsin real estate holding company. The financial statements of the Bank also include one wholly-owned limited liability corporation (LLC) formed to own certain of the Bank’s foreclosed properties. All significant intercompany balances and transactions have been eliminated in consolidation. Jumpstart Our Business Startups Act: The Jumpstart Our Business Startups Act (the JOBS Act), which was signed into law on April 5, 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.0 billion during its most recently completed fiscal year qualifies as an “emerging growth company.” The Company qualifies as an “emerging growth company” and believes that it will continue to qualify as an “emerging growth company” until five years from the completion of the stock offering, which occurred on April 9, 2013. As an “emerging growth company,” the Company has elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, the financial statements may not be comparable to the financial statements of companies that comply with such new or revised accounting standards. Use of estimates: In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, valuation of deferred tax assets and valuation of mortgage servicing rights. Cash and cash equivalents: For purposes of the consolidated statements of cash flows, cash and cash equivalents includes cash, due from banks, and interest-bearing deposits. The Company maintains amounts due from banks that, at times, may exceed federally insured limits. Management monitors these correspondent relationships and has experienced no losses. Accordingly, in the opinion of management, no material risk of loss exists. Securities: Unless classified as "held-to-maturity", all securities are classified as “available-for-sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in accumulated other comprehensive income, net of the related deferred tax effect. Securities are classified as "held-to-maturity" and recorded at amortized cost when management has the ability and intent to hold the securities to maturity. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of individual available-for-sale securities below their amortized cost basis that are deemed to be other-than-temporary impairment losses are reflected as realized losses. In determining whether an other-than-temporary impairment exists, management considers many factors including (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent or requirement of the Company to sell its investment in the issuer prior to any anticipated recovery in fair value. If the Company intends to sell an impaired security, it records an other-than-temporary loss in an amount equal to the entire difference between the fair value and amortized cost of the security. If a security is determined to be other-than-temporarily impaired, but the Company does not intend to sell the security, only the credit portion of the estimated loss is recognized in earnings, with the other portion of the loss recognized in other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as estimated based on cash flow projections discounted at the applicable original yield of the security. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Loans held for sale: Loans held for sale are recorded at the lower of cost or fair value as determined on an aggregate basis. Fees received from the borrower and the direct costs of loan originations are deferred and recorded as an adjustment to the sales price, when such loans are sold. Loans: The Company grants commercial, mortgage and consumer loans to customers principally located in Southeastern Wisconsin. The ability of the Company’s loan customers to meet the terms of their loans is dependent upon the general economic conditions in this area and real estate values. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are generally reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and deferred loan fees or costs on an originated basis. Interest income is accrued on the unpaid principal balance. Loan origination and commitment fees and certain direct loan origination costs on loans receivable are deferred, and the net amounts amortized as an adjustment of the related loan’s yield. These amounts are amortized, using the level-yield method, over the contractual life of the related loans. Unamortized deferred amounts are included in interest income upon repayment or sale of the related loan. The accrual of interest on loans is discontinued at the time the loan is ninety days delinquent, unless the loan is well-secured and in the process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Allowance for loan losses: For all portfolio segments, the allowance for loan losses is maintained at the level considered adequate by management of the Company to provide for losses that are probable. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. In determining the adequacy of the allowance balance, the Company makes continuous evaluations of the loan portfolio and related off-balance sheet commitments, considers current economic conditions and historical loss experience, and reviews specific problem loans and other factors. When establishing the allowance for loan losses, management categorizes loans into risk categories generally based on the nature of the collateral and the basis of repayment. These risk categories and their relevant risk characteristics are as follows: Single family: Single family loans are real estate loans generally smaller in size and are homogeneous because they exhibit similar characteristics. Single family loans are underwritten by evaluating the credit history of the borrower, the ability of the borrower to meet the debt service requirements of the loan and total debt obligations, as well as the underlying collateral and the loan to collateral value. Also included in this category are junior liens on 1-4 family residential properties. These loans consist of closed-end loans secured by junior liens on 1-4 family residential properties. Underwriting standards for single family loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements. Construction and land development: These loans are secured by vacant land and/or property that are in the process of improvement, including (a) land development preparatory to erecting vertical improvements or (b) the on-site construction of industrial, commercial, residential, or farm buildings. Repayment of these loans can be dependent on the sale of the property to third parties or the successful completion of the improvements by the builder for the end user. For purposes of this classification, “construction” includes not only construction of new structures, but any loans originated to finance additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Until a permanent loan originates, or payoff occurs, all construction loans secured by real estate are reported in this loan pool. Loans to finance construction and land development that are not secured by real estate are segmented and reported separate from this pool. In the event a loan is made on property that is not yet improved for the planned development, there is the risk that necessary approvals will not be granted or will be delayed. Construction loans also run the risk that improvements will not be completed on time or in accordance with specifications and projected costs. Commercial business: Commercial business loans are extended primarily to middle market customers. Such credits typically comprise working capital loans, loans for physical asset expansion, asset acquisition loans and other business loans. Loans to closely held businesses will generally be guaranteed in full or for a meaningful amount by the owners of the business. Commercial business loans are made based primarily on the historical and projected cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors. Minimum standards and underwriting guidelines have been established for all commercial and industrial loan types. Multifamily: Multifamily loans include loans to finance non-farm properties with five or more units in structures primarily to accommodate households on a temporary or permanent basis. Such credits are typically originated to finance the acquisition of an apartment or condo building/complex. Multifamily loans are made based primarily on the historical and projected cash flow of the subject multifamily property, with assumptions made for vacancy rates. Cash flows and ultimate loan performance rely on the receipt of rental income from the tenants of the property who are themselves subject to fluctuations in national and local economic and unemployment trends. Commercial real estate: These loans are primarily secured by office and industrial buildings, warehouses, small retail shopping facilities and various special purpose properties, including hotels and restaurants. These loans are subject to underwriting standards and processes similar to commercial business loans. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type. Consumer and other: These loans may take the form of installment loans, demand loans, or single payment loans, and are extended to individuals for household, family, and other personal expenditures. These include direct consumer automobile loans extended by the Company for the purpose of purchasing a new or used vehicle for personal use. Consumer and installment loans are underwritten by evaluating the credit history of the borrower and the ability of the borrower to meet the debt service requirements of the loan and total debt obligations. Also included in this category are home equity lines of credit. These loans consist of revolving open-end lines of credit secured by 1-4 family residential properties extended to individuals for household, family or other personal expenditures. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. In addition, regulatory agencies, as an integral part of their examination processes, periodically review the Company’s allowance for loan losses, and may require the Company to recognize adjustments to its allowance based on their judgments of information available to them at the time of their examinations. The allowance consists of specific and general components. The specific component relates to loans that are classified as impaired, and an allowance is established when the collateral value, discounted cash flows or observable market price of the impaired loan are lower than the carrying value of that loan. The general component covers non-impaired loans and is based on the Company’s own loss experience over the most recent seventeen quarters, adjusted for qualitative factors. These qualitative factors consider local economic trends, concentrations, management experience and other elements of the Company’s lending operations. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining the impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the fair value of collateral, if the loan is collateral dependent, the present value of expected future cash flows discounted at the loan’s effective interest rate, or the loan’s obtainable market price. Single family and consumer and other loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual homogeneous loans for impairment disclosures, unless such loans are the subject of a restructuring agreement due to the financial difficulties of the borrower, the loans are related with another commercial type loan or the loans experience significant payment delinquencies and are not insured. Troubled debt restructurings: Loans are accounted for as troubled debt restructurings when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants a “concession” to the borrower that they would not otherwise consider. These concessions include a modification of terms such as a reduction of the stated interest rate or loan balance, a reduction of accrued interest, an extension of the maturity date at an interest rate lower than a current market rate for a new loan with similar risk, or some combination thereof to facilitate repayment. Troubled debt restructurings are classified as impaired loans. Payment performance prior and subsequent to the restructuring is taken into account in assessing whether it is likely that the borrower can meet the new terms. A period of sustained repayment, for at least six months, is generally required for return to accrual status. This may result in the loan being returned to accrual at the time of restructuring. A loan that is modified at a market rate of interest will not be classified as a troubled debt restructuring or impaired in the calendar year subsequent to the restructuring if it is in compliance with the modified terms. Federal Home Loan Bank stock: Federal Home Loan Bank (FHLB) stock consists of the Company’s required investment in the capital stock of the FHLB. No ready market exists for these securities and they have no quoted market value; as such the stock is carried at cost. Management reviews for impairment based on the ultimate recoverability of the cost basis in the FHLB stock, and no impairment has been identified as a result of these reviews. Foreclosed real estate: Real estate acquired by foreclosure or by deed in lieu of foreclosure is initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Costs relating to the development and improvement of property are capitalized; holding costs are charged to expense. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of their carrying amount or fair value less cost to sell. Revenues and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed real estate. Real estate held for investment/sale: Real estate held for investment consists of rental properties. Rental properties are carried at the lower of cost less provisions for depreciation computed by the straight-line method over the estimated life of the property. Rental revenue is recognized on a straight-line basis over the term of the lease unless another systemic and rational basis is more representative of the time pattern in which the use benefit is derived from the leased property, or fair value less costs to sell. The difference between rental income earned on a straight-line basis and the cash rent due under provisions of the lease agreements is recorded as deferred rent receivable and is included as a component of other assets in the accompanying consolidated balance sheets. A property is considered held for sale when a contract for sale is entered into or when management has committed to a plan to sell an asset, the asset is actively marketed, and sale is expected to occur within one year. Property reported as held for sale is reported at the lower of the carrying amount or fair value less costs to sell and is not depreciated. The Company evaluates the carrying value of all real estate held when an indicator of impairment is deemed to exist. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount which the carrying amount of the asset exceeds the fair value of the asset. Office properties and equipment: Office properties including equipment are stated at cost less accumulated depreciation, and include expenditures for new facilities and items that substantially increase the useful lives of existing buildings and equipment. Expenditures for normal repairs and maintenance are charged to expense as incurred. When properties are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recorded. Cash surrender value of life insurance: The Company has purchased bank-owned life insurance policies on certain executives. Bank-owned life insurance is recorded at its cash surrender value. Changes in the cash surrender values are included in non-interest income. Mortgage servicing rights: Mortgage servicing rights (MSRs) are initially recognized at fair value when loans have been sold to investors and are amortized over the lives of the loans. Upon sale of loans with servicing retained, the servicing rights are recorded at fair value and remaining proceeds received are allocated to the loan. Amortization of MSRs is based on the ratio of net servicing income received in the current period, to total remaining net servicing income projected to be realized from the MSRs. MSRs are periodically assessed for impairment, which is calculated using estimated net cash flow analysis on a discounted basis. Impairment is recognized in the statement of income, during the period in which it occurs, as an adjustment to the corresponding valuation allowance. For purposes of performing an impairment evaluation, the serviced loan portfolio is stratified on the basis of certain risk characteristics including loan type (i.e., fixed or adjustable interest rates). Transfers of financial assets: Transfers of financial assets are accounted for as sales only when the control over the financial assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. Employee stock ownership plan: The Company has an employee stock ownership plan (ESOP) covering substantially all employees. The cost of shares issued to the ESOP but not yet allocated to participants is presented in the consolidated balance sheets as a reduction of stockholders' equity. Compensation expense is recorded based on the market price of the shares as they are committed to be released for allocation to participant accounts. Stock-based compensation: The Company accounts for its equity awards in accordance with ASC Topic 718. ASC Topic 718 requires public companies to recognize compensation expense related to stock-based equity awards in their income statements. See Note 14 below for more information. Income taxes: The Company, the Bank, and its subsidiaries file consolidated federal income tax returns and combined state income tax returns. Accordingly, amounts equal to tax benefits of those companies having taxable federal losses or credits are reimbursed by the other companies that incur tax liabilities. Deferred income taxes are provided using the liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of the changes in tax laws and rates as of the date of enactment. The Company accounts for uncertainty in income taxes to determine whether tax benefits claimed or expected to be claimed on a tax return, should be recorded in the consolidated financial statements. The Company may recognize the tax benefit for an uncertain tax position if it is more-likely-than-not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being utilized upon ultimate settlement. It is the Company’s policy that interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statement of operations. Derivative financial instruments and hedging activities: All derivatives are recognized in the consolidated balance sheets at their fair value. Derivative contracts are maintained related to commitments to fund residential mortgages (interest rate locks) in connection with residential mortgages intended for sale. Such commitments are recorded at fair value in other assets or liabilities, with changes in fair value recorded in net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements, and for fixed rate commitments, also considers the committed rates and current levels of interest rates. Derivative contracts are also maintained related to certificates of deposit, for which changes in the fair value of the derivative are recorded in earnings. Comprehensive income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available-for-sale, which are also recognized as separate components of equity. Reclassification: Certain amounts in the 2014 consolidated financial statements have been reclassified to conform to the 2015 presentation. These reclassifications had no effect on net income or loss. Segment reporting: The Company views the Bank as one operating segment, therefore, separate reporting of financial segment information is not considered necessary. The Company approaches the Bank and its other subsidiaries as one business enterprise, which operates in a single economic environment, since the products and services, types of customers and regulatory environment all have similar characteristics. Recent accounting pronouncements: In January 2014, the FASB issued ASU 2014-04, Receivables (Topic 310) - Troubled Debt Restructurings by Creditors. ASU 2014-04 is intended to reduce diversity by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU 2014-04 is effective for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 15, 2015. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 is intended to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2018 and interim periods within annual periods beginning after December 15, 2019. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures. In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing (Topic 860) - Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. ASU 2014-11 is intended to clarify the accounting for and improve the disclosures related to repurchase-to-maturity transactions and repurchase financings. ASU 2014-11 is effective for annual periods beginning after December 15, 2014 and interim periods within annual periods beginning after December 15, 2015. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures. In June 2014, the FASB issued ASU 2014-12, Compensation - Stock Compensation (Topic 718) - Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved After the Requisite Service Period. ASU 2014-12 is intended to clarify the accounting for the timing of expense recognition related to employee share-based payments in which a performance target that effects vesting could be achieved after the requisite service period. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures. In August 2014, the FASB issued ASU 2014-14, Receivables - Troubled Debt Restructuring by Creditors (Topic 310) - Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure. ASU 2014-14 is intended to clarify the accounting for and improve the consistency of balance sheet classification of certain foreclosed mortgage loans that are either fully or partially guaranteed under government programs. Greater consistency in classification of such mortgage loans upon foreclosure is expected to provide more decision-useful information about a creditor's foreclosed mortgage loans that are expected to be recovered, at least in part, through government guarantees. ASU 2014-14 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures.

At September 30, 2014 , the investment portfolio included 63 securities available-for-sale which had been in unrealized loss positions for greater than twelve months and 25 securities which had been in unrealized loss positions for less than twelve months. These securities are considered to be acceptable credit risks. Based upon an evaluation of the available evidence, including recent changes in market rates, credit rating information and information obtained from regulatory filings, management believes the decline in fair value for these securities is temporary. In addition, the Company does not intend to sell these investment securities for a period of time sufficient to allow for anticipated recovery. The Company does not have any current requirement to sell its investment in the issuer prior to any anticipated recovery in fair value.

The Company considers current financial information, historical payment experience, credit documentation, public information and current economic trends. Generally, all sizable credits receive a financial review no less than annually to monitor and adjust, if necessary, the credit’s risk profile. Credits classified as watch, special mention, substandard and doubtful generally receive a review quarterly. The Company categorizes loans into the following risk categories based on relevant information about the ability of borrowers to service their debt: Pass - A pass asset is well protected by the current worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less costs to acquire and sell in a timely manner, of any underlying collateral. Watch - A watch asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Watch assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Special Mention - A special mention asset has characteristics of deterioration in quality exhibited by any number of well-defined weaknesses requiring significant corrective action. The repayment ability of the borrower has not been validated, or has become marginal or weak and the loan may have exhibited some overdue payments or payment extensions and/or renewals. Substandard - A substandard asset is an asset with a well-defined weakness that jeopardizes repayment in whole, or in part, of the debt. These credits are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged. These assets are characterized by the distinct possibility that the Company will or has sustained some loss of principal and/or interest if the deficiencies are not corrected. Doubtful - A doubtful asset is an asset that has all the weaknesses inherent in the substandard classification with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. These credits have a high probability for loss, yet because certain important and reasonably specific pending factors may work toward the strengthening of the asset, its classification of loss is deferred until its more exact status can be determined. Homogeneous loan types are assessed for credit quality based on the contractual aging status of the loan and payment activity. In certain cases, based upon payment performance, the loan being related with another commercial type loan or for other reasons, a loan may be categorized into one of the risk categories noted above. Such assessment is completed at the end of each reporting period. The following tables present the risk category of loans evaluated by internal asset classification based on the most recent analysis performed and the contractual aging as of September 30, 2015 and 2014 : September 30, 2015 Pass Watch Special Mention Substandard Doubtful Total (In thousands) Single family $ 150,421 $ 1,135 $ — $ 1,585 $ — $ 153,141 Multifamily 103,117 2,633 — — — 105,750 Commercial real estate 159,104 3,136 410 307 — 162,957 Construction and land development 18,831 — — — — 18,831 Commercial business 36,561 — — 1,639 — 38,200 Consumer and other: Home equity lines of credit 14,636 — — 245 — 14,881 Education 4,106 — — — — 4,106 Other 523 — — — — 523 Total $ 487,299 $ 6,904 $ 410 $ 3,776 $ — $ 498,389 September 30, 2014 Pass Watch Special Mention Substandard Doubtful Total (In thousands) Single family $ 132,067 $ 1,317 $ 118 $ 1,835 $ — $ 135,337 Multifamily 73,876 1,915 445 160 — 76,396 Commercial real estate 126,319 6,117 858 1,827 — 135,121 Construction and land development 16,357 — — 5 — 16,362 Commercial business 34,112 3,459 — 104 — 37,675 Consumer and other: Home equity lines of credit 14,088 — — 187 — 14,275 Education 4,694 — — — — 4,694 Other 1,319 — — 2 — 1,321 $ 402,832 $ 12,808 $ 1,421 $ 4,120 $ — $ 421,181 The following tables provide additional detail of the activity in the allowance for loan losses, by portfolio segment, for the years ended September 30, 2015 and 2014 : Year Ended Commercial Construction and Commercial Consumer September 30, 2015 Single Family Multifamily Real Estate Land Development Business and Other Total (In thousands) Allowance for loan losses: Beginning balance $ 1,072 $ 757 $ 1,412 $ 301 $ 454 $ 76 $ 4,072 Provision for loan losses 240 355 271 29 36 19 950 Loans charged-off (257 ) (99 ) (115 ) — (14 ) (26 ) (511 ) Recoveries 18 — 36 — 22 11 87 Ending balance $ 1,073 $ 1,013 $ 1,604 $ 330 $ 498 $ 80 $ 4,598 Period-ended amount allocated for: Individually evaluated for impairment $ 22 — $ — $ — $ — $ 55 $ 77 Collectively evaluated for impairment 1,051 1,013 1,604 330 498 25 4,521 Ending Balance $ 1,073 $ 1,013 $ 1,604 $ 330 $ 498 $ 80 $ 4,598 Loans: Individually evaluated for impairment $ 1,595 $ 1,832 $ — $ — $ — $ 225 $ 3,652 Collectively evaluated for impairment 151,546 103,918 162,957 18,831 38,200 19,285 494,737 Ending Balance $ 153,141 $ 105,750 $ 162,957 $ 18,831 $ 38,200 $ 19,510 $ 498,389 Year Ended Commercial Construction and Commercial Consumer September 30, 2014 Single Family Multifamily Real Estate Land Development Business and Other Total (In thousands) Allowance for loan losses: Beginning balance $ 1,873 $ 165 $ 1,501 $ 374 $ 211 $ 142 $ 4,266 Provision for loan losses (92 ) 588 130 (83 ) 359 (352 ) 550 Loans charged-off (870 ) — (254 ) — (159 ) (53 ) (1,336 ) Recoveries 161 4 35 10 43 339 592 Ending balance $ 1,072 $ 757 $ 1,412 $ 301 $ 454 $ 76 $ 4,072 Period-ended amount allocated for: Individually evaluated for impairment $ 40 — $ 38 $ — $ — 58 $ 136 Collectively evaluated for impairment 1,032 757 1,374 301 454 18 3,936 Ending Balance $ 1,072 $ 757 $ 1,412 $ 301 $ 454 $ 76 $ 4,072 Loans: Individually evaluated for impairment $ 1,734 $ 1,915 $ 630 $ — $ — $ 203 $ 4,482 Collectively evaluated for impairment 133,603 74,481 134,491 16,362 37,675 20,087 416,699 Ending Balance $ 135,337 $ 76,396 $ 135,121 $ 16,362 $ 37,675 $ 20,290 $ 421,181 The following tables present additional detail of impaired loans, segregated by segment, as of and for the years ended September 30, 2015 and 2014 .

Advances From the Federal Home Loan Bank	Advances From the Federal Home Loan Bank The Bank maintains a master contract agreement with the Federal Home Loan Bank of Chicago (FHLB) that provides for borrowing up to the maximum of 75 percent of the book value of the Bank’s first lien 1-4 family real estate loans. The FHLB provides both fixed and floating rate advances. Floating rates are tied to short-term market rates of interest, such as LIBOR, Federal Funds or Treasury Bill rates. Fixed rate advances are priced in reference to market rates of interest at the time of the advance, namely the rates that the FHLB pays to borrowers at various maturities. Interest is payable monthly with principal payable at maturity. Advances are generally secured by a security agreement pledging a portion of the Bank’s residential real estate loans. Pledged real estate mortgages and home equity lines of credit had a carrying value of $150,226 and $136,476 as of September 30, 2015 , and September 30, 2014 , respectively.

Regulatory Capital

Regulatory Capital Requirements [Abstract]
Regulatory Capital	Regulatory Capital The federal banking agencies have adopted regulations that substantially amend the capital regulations currently applicable to us. These regulations implement the Basel III regulatory capital reforms and changes required by the Dodd-Frank Act. Effective January 1, 2015 (with some changes transitioned into full effectiveness over two to four years), the Bank became subject to new capital requirements adopted by the OCC. These new requirements create a new required ratio for common equity Tier 1 ("CETI") capital, increase the leverage and Tier 1 capital ratios, change the risk weight of certain assets for purposes of the risk-based capital ratios, create an additional capital conservation buffer over the required capital ratios and change what qualifies as capital for purposes of meeting these various capital requirements. Beginning in 2016, failure to maintain the required capital conservation buffer will limit the ability of the Bank to pay dividends, repurchase shares or pay discretionary bonuses. The Company is exempt from consolidated capital requirements as those requirements do not apply to certain small savings and loan holding companies with assets under $1 billion. Under the new capital regulations, the minimum capital ratios are: (1) CETI capital ratio of 4.5% of risk-weighted assets; (2) a Tier 1 capital ratio of 6.0% of risk-weighted assets: (3) a total capital ratio of 8.0% of risk-weighted assets; and (4) a leverage ratio of 4.0%. CETI generally consists of common stock and retained earnings, subject to applicable regulatory adjustments and deductions. There are a number of changes in what constitutes regulatory capital, some of which are subject to transition periods. These changes include the phasing-out of certain instruments as qualifying capital. The Bank does not use any of these instruments. Under the new requirements for total capital, Tier 2 capital is no longer limited to the amount of Tier 1 capital included in total capital. Mortgage servicing rights, certain deferred tax assets and investments in unconsolidated subsidiaries over designated percentages of CETI will be deducted from capital. The Bank has elected to permanently opt-out of the inclusion of accumulated other comprehensive income in our capital calculations, as permitted by the regulations. This opt-out will reduce the impact of market volatility on our regulatory capital levels. The new requirements also include changes in the risk-weights of assets to better reflect credit risk and other risk exposures. These include a 150% risk weight (increased from 100%) for certain high volatility commercial real estate acquisition, development and construction loans and for non-residential mortgage loans that are 90 days past due or otherwise in non-accrual status; a 20% (increased from 0%) credit conversion factor for the unused portion of a commitment with an original maturity of one year or less that is not unconditionally cancellable; a 250% risk weight (increased from 100%) for mortgage servicing and deferred tax assets that are not deducted from capital; and increased risk weights (0% to 600%) for equity exposures. In addition to the minimum CETI, Tier 1 and total capital ratios, the Bank will have to maintain a capital conservation buffer consisting of additional CETI capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses based on percentages of eligible retained income that could be utilized for such actions. This new capital conservation buffer requirement will be phased in beginning in January 2016 at 0.625% of risk-weighted assets and increasing each year until fully implemented in January 2019. The OCC's prompt corrective action standards also changed effective January 1, 2015. Under the new standards, in order to be considered well-capitalized, the Bank must have a CETI ratio of 6.5% (new), a Tier 1 ratio of 8.0% (increased from 6.0%), a total risk-based capital ratio of 10.0% (unchanged) and a leverage ratio of 5.0% (unchanged). The Bank meets all these new requirements, including the full capital conservation buffer.

Compensation and Retirement Disclosure [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Bank maintains a contributory, defined-contribution profit-sharing plan (the "Plan") for all employees meeting certain minimum age and service requirements. The Plan qualifies under Section 401(k) of the Internal Revenue Code. Participants may elect to defer a portion of their compensation (between 2 percent and 10 percent ) and contribute this amount to the Plan. A discretionary contribution is made each year as determined annually by the Board of Directors. The contribution is allocated to each participant based on his or her compensation. The aggregate benefit payable to any employee is dependent upon his or her rate of contribution, the earnings of the Plan assets, and the length of time such employee has been a participant in the Plan. The expense related to this Plan was $171 and $176 for the years ended September 30, 2015 and 2014 , respectively. The Bank maintains a leveraged employee stock ownership plan ("ESOP") that covers all employees meeting certain minimum age and service requirements. The ESOP was established in conjunction with the Company's stock offering completed in April 2013 and operates on a plan year ending December 31. The ESOP initially borrowed $4.1 million and used those funds to acquire 411,403 shares, or 8.0% of the total number of shares issued by the Company in its initial public offering. The shares were acquired at a price of $10.00 per share. The Bank makes annual contributions to the ESOP equal to the ESOP's debt service. The ESOP shares were pledged as collateral for its debt. As the debt is repaid, shares are released from collateral and allocated to active participants, based on the proportion of debt service paid in the year. The Company accounts for its ESOP in accordance with ASC 718-40. Accordingly, because the debt is intercompany, it is eliminated in consolidation for presentation in these financial statements. The shares pledged as collateral are reported as unearned ESOP shares in the balance sheet. Total ESOP shares may be reduced as a result of employees leaving the Company as shares that have previously been released to those exiting employees may be removed from the ESOP and transferred to that employee. As shares are committed to be released from collateral, the Company reports compensation expense equal to the current market price of the shares, and the shares become outstanding for EPS computations. During each of 2015 and 2014, 20,570 shares were committed to be released resulting in ESOP compensation expense of $378 and $320 for the years ended September 30, 2015 and 2014, respectively. The ESOP shares as of September 30 were as follows: September 30, 2015 September 30, 2014 Shares allocated to active participants 34,132 20,570 Shares committed to be released 15,428 15,428 Unallocated shares 354,835 375,405 Total ESOP shares 404,395 411,403 Fair value of unallocated shares $ 6,323 $ 5,650

The following table summarizes the impact of the Company's share-based payment plans in the financial statements for the periods shown: Years Ended September 30, 2015 2014 (In thousands) Total cost of stock grant plan during the year $ 614 $ 165 Total cost of stock option plan during the year 195 49 Total cost of share-based payment plans during the year $ 809 $ 214 Amount of related income tax benefit recognized in income $ 317 $ 84 The Company adopted the Westbury Bancorp Inc 2014 Equity Incentive Plan (the "Plan") in 2014. In June 2014, the Company's stockholders approved the Plan which authorized the issue of up to 203,665 restricted stock awards and up to 509,162 stock options. As of September 30, 2015 there were 5,092 restricted stock awards and 102,753 options available for future grants. Annual equity-based incentive awards are typically granted to selected officers and employees mid-year. Options are granted with an exercise price equal to no less than the market price of the Company's shares at the date of grant: those option awards generally vest over five years of service and have 10 -year contractual terms. Restricted shares and units typically vest over a five year period. Equity awards may also be granted at other times throughout the year in connection with the recruitment and retention of officers and employees. The following table summarizes stock options outstanding for the year ended September 30, 2015: Number of Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Options outstanding as of September 30, 2014 326,224 $ 15.20 Granted 89,729 17.37 Exercised — — Expired or canceled — — Forfeited (9,544 ) 15.20 Options outstanding as of September 30, 2015 406,409 $ 15.68 8.98 $ 872 Options exercisable as of September 30, 2015 65,244 $ 15.20 8.75 $ 171 The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model based on certain assumptions. Since the Company's stock has traded for less than three years, expected volatility is based on the average volatility of an index of publicly-traded, small community bank stocks and the expectations of future volatility of Company shares. The risk free interest rate for periods within the contractual term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. SInce options were first awarded in June 2014 and the Company has not yet had options exercised by participants in the plan, the expected life of options is estimated based on the assumption that options will be exercised evenly throughout their life after vesting and represents the period of time that options granted are expected to remain outstanding. The following assumptions were used for options granted during the years ended September 30, 2015 and 2014: For the Years Ended September 30, 2015 2014 Risk-free interest rate 2.09 % 2.10 % Expected volatility 7.44 % 9.49 % Expected dividend yield — % — % Expected life of options (years) 7.5 7.5 Weighted average fair value per option of options granted during the year $ 2.94 $ 2.82 The total intrinsic value of options exercised during the years ended September 30, 2015 and 2014 was $0 and $0 , respectively. The following is a summary of changes in restricted shares and units for the year ended September 30, 2015: Number of Shares Weighted Average Grant Date Fair Value Shares and Units Outstanding at September 30, 2014 203,665 $ 15.20 Granted — — Vested (40,521 ) 15.20 Forfeited (5,092 ) 15.20 Shares and Units Outstanding at September 30, 2015 158,052 $ 15.20 The total intrinsic value of restricted shares that vested during the years ended September 30, 2015 and 2014 was $703,000 and $0 , respectively. As of September 30, 2015, there was $3.3 million of total unrecognized compensation cost related to nonvested share-based compensation arrangements (including share option and nonvested share awards) granted under the Plan. At September 30, 2015, the weighted-average period over which the unrecognized compensation expense is expected to be recognized was approximately 3.83 years .

Deferred Compensation Arrangements [Abstract]
Deferred Compensation	Deferred Compensation Certain key employees of Westbury Bank hold non-qualified salary continuation plans. These plans provide for payments of specific amounts over 10 to 20 year periods subsequent to each participant’s retirement. The related deferred compensation liabilities are being accrued ratably to the respective normal retirement dates of each participant. As of September 30, 2015 and 2014 , approximately $1,996 and $2,078 are accrued related to these plans. The expense for compensation under these plans was approximately $59 and $178 for the years ended September 30, 2015 and 2014 , respectively. Although not part of the plans, the Company has purchased life insurance on the lives of certain employees electing to participate in the plans, which could provide funding for the payment of benefits. At September 30, 2015 and 2014 , the cash surrender value of such life insurance policies totaled $13,167 and $12,742 , respectively. The Company currently defers its Directors’ fees at the discretion of the Director, with payments made at the request of each Director. The balances of deferred directors’ fees were $623 and $659 at September 30, 2015 and 2014 , respectively.

Guarantees [Abstract]
Guarantees	Guarantees The Bank has executed commitments under the Mortgage Partnership Finance (MPF) program with the FHLB to guarantee the payment of any realized losses that exceed the FHLB’s first loss account for mortgages delivered under the commitments. The Bank receives credit enhancement fees from the FHLB for providing this guarantee and continuing to manage the credit risk of the MPF program mortgage loans. The liability representing the present value of the credit enhancement fees less any expected losses in the mortgages delivered under the commitments was not material. The maximum potential amount of future payments that the Bank could be required to make under the limited recourse guarantee was approximately $1,109 and $1,248 at September 30, 2015 and 2014 . Under the commitments, the Bank agrees to service the loans and therefore, is responsible for any necessary foreclosure proceedings. Any future recoveries on any losses would not be paid by the FHLB under the commitments. Historically, the Bank has not incurred a loss on loans sold to the FHLB with these recourse provisions and management has determined there are no probable losses related to these loans at September 30, 2015 , or 2014 .

The carryforwards start to expire in 2024. The Company has federal net operating loss carryforwards of approximately $10,904 and $13,806 at September 30, 2015 and 2014 , respectively, which can be used to offset its future federal taxable income. The carryforwards start to expire in 2030. The Internal Revenue Code of 1986, as amended, imposes an alternative minimum tax at a rate of 20% on a base of regular taxable income plus certain tax preferences, referred to as “alternative minimum taxable income.” The alternative minimum tax is payable to the extent alternative minimum taxable income is in excess of an exemption amount. Net operating losses can, in general, offset no more than 90% of alternative minimum taxable income. Certain payments of alternative minimum tax may be used as credits against regular tax liabilities in future years. At September 30, 2015, the Company had $533 of minimum tax credit carryforwards which do not expire. In assessing the reliability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management performed an evaluation of the Company's deferred tax assets as of September 30, 2015 and 2014. In making the determination whether a deferred tax asset is more likely than not to be realized, we seek to evaluate all available positive and negative evidence. Negative evidence considered included our recent pre-tax losses and our relatively high level of net loan charge-offs, loan loss provisions and OREO losses from 2009 through 2014. Positive evidence reviewed included our historical earnings performance prior to the recession and during the year just ended, our projected earnings forecast, significantly reduced levels of non-performing assets, loan loss provisions and net charge-offs in 2015, the reduction of credit risk in our loan portfolio, and potential use of tax strategies. Based on our analysis at September 30, 2015 and September 30, 2014, including evidence related to the substantially reduced risk profile of the loan portfolio and our improved earnings forecasts (supported by the growth in net interest income and the reduction of operating expenses) we concluded that there is more positive evidence than negative regarding the utilization of our deferred tax asset and that the recorded deferred tax asset, with no valuation reserve required at September 30, 2015, and net of the recorded valuation reserve of $2,447 at September 30, 2014, is realizable. Under the Internal Revenue Code and Wisconsin Statutes, the Bank is permitted to deduct, for tax years beginning before 1997, an annual addition to a reserve for bad debts. The amount differs from the provision for loan losses recorded for financial accounting purposes. Under prior law, bad debt deductions for income tax purposes were included in taxable income of later years only if the bad debt reserves were used for purposes other than to absorb bad debt losses. Because the Company did not intend to use the reserve for purposes other than to absorb losses, no deferred income taxes were provided. Retained earnings as of September 30, 2015 and 2014 , include approximately $3,227 for which no deferred federal or state income taxes were provided. If in the future the Company no longer qualifies as a bank for tax purposes, an income tax expense of $1,266 would be incurred. The Company files income tax returns in the U.S. federal jurisdiction and the state of Wisconsin. With few exceptions, the Company is no longer subject to U.S. federal tax examinations by tax authorities for years before 2011 and state tax examinations by tax authorities for years before 2010.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contractual amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. The following instruments were outstanding whose contract amounts represent credit risk: September 30, September 30, Commitments to extend mortgage credit: Fixed rate $ 8,443 $ 960 Adjustable rate 9,929 3,339 Unused commercial loan lines of credit 54,225 38,966 Unused home equity line of credit 26,164 22,359 Standby letters of credit 884 422 Commitment to sell loans 431 326 Commitments to extend credit are agreements to lend funds to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. As some such commitments expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The Company generally extends credit only on a secured basis. Collateral obtained varies but consists primarily of one-to-four family residences. Unfunded commitments under lines of credit are commitments for possible future extensions of credit to existing customers. These lines of credit may be uncollateralized and ultimately may not be drawn upon to the total extent to which the Company is committed. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those letters of credit are primarily issued to support public and private borrowing arrangements, and, generally, have terms of one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company holds collateral supporting those commitments if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount shown in the summary above. If the commitment is funded, the Company would be entitled to seek recovery from the customer. At September 30, 2015 and 2014 , no amounts have been recorded as liabilities for the Company’s potential obligations under these guarantees. Litigation In the normal course of business, the Company is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the Company’s consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Activities	Derivative Activities The Company has on deposit certain certificates of deposit with embedded derivatives where the related interest earned by the account holder is calculated based on changes in the S&P 500. The Company enters into interest rate swaps and options to offset the variability in interest expense related to these certificates of deposits. At September 30, 2015 and 2014 , the Company had approximately $377 and $587 , respectively, in notional amount of swaps where the Company pays a fixed or LIBOR-based interest rate and receives a variable rate based on the S&P 500. The fair values of the embedded derivatives, swaps and options are reported in the consolidated balance sheets, and the changes in fair value of the embedded derivatives, swaps and options are reported as gains or losses in the consolidated statements of operations. The fair value of the derivative liability was $110 and $87 as of September 30, 2015 and 2014 , respectively, and the related derivative asset was $110 and $87 as of September 30, 2015 and 2014 , respectively. The change in fair value was not significant as of September 30, 2015 and 2014 . Commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans are defined as derivatives. The fair value related to these commitments was not material as of September 30, 2015 and 2014 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. ASC Topic 820 requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, ASC Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Securities available-for-sale : The fair value of the Company’s securities available-for-sale is determined using Level 2 inputs, which are derived from readily available pricing sources and third-party pricing services for comparable instruments. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, treasury yield curves, trading levels, credit information and credit terms, among other factors. In certain cases where Level 1 or Level 2 are not available, securities are classified within Level 3 of the hierarchy. Derivatives : The fair values of the Company’s embedded derivatives related to certain certificates of deposit are determined using inputs that are observable or that can be corroborated by observable market data (such as the S&P 500 Index and the 10-year U.S. Treasury rate) and, therefore, are classified within Level 2 of the valuation hierarchy. Assets and liabilities recorded at fair value on a recurring basis : The following table summarizes assets measured at fair value on a recurring basis, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value as of: Fair Value Measurements September 30, 2015 Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) (In thousands) Assets Securities available-for-sale U.S. Government and agency securities $ 25 $ — $ 25 $ — U.S. Government agency residential mortgage-backed securities 39,692 — 39,692 — U.S. Government agency collateralized mortgage obligations 1,941 — 1,941 — U.S. Government agency commercial mortgage-backed securities 14,099 — 14,099 — Municipal securities 21,667 — 21,667 — Corporate Bonds 2,862 — 2,862 — Total securities available-for-sale $ 80,286 $ — $ 80,286 $ — Derivatives $ 110 $ — $ 110 $ — Liabilities Derivatives $ 110 $ — $ 110 $ — Fair Value Measurements September 30, 2014 Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) (In thousands) Assets Securities available-for-sale U.S. Government and agency securities $ 5,179 $ — $ 5,179 $ — U.S. Government agency residential mortgage-backed securities 37,196 — 37,196 — U.S. Government agency collateralized mortgage obligations 3,432 — 3,432 — U.S. Government agency commercial mortgage-backed securities 10,752 — 10,752 — Municipal securities 33,787 — 33,787 — Corporate Bonds — — Total securities available-for-sale $ 90,346 $ — $ 90,346 $ — Derivatives $ 87 $ — $ 87 $ — Liabilities Derivatives $ 87 $ — $ 87 $ — The Company did not have any transfers between Level 1, Level 2, and Level 3 of the fair value hierarchy during the years ended September 30, 2015 and 2014. The Company’s policy for determining transfers between levels occurs at the end of the reporting period when circumstances in the underlying valuation criteria change and result in a transfer between levels. Assets recorded at fair value on a nonrecurring basis : The Company may be required, from time to time, to measure certain instruments at fair value on a nonrecurring basis in accordance with U.S. generally accepted accounting principles. Impaired loans : The Company does not record loans at fair value on a recurring basis. The specific reserves for collateral-dependent impaired loans are based on the fair value of the collateral less estimated costs to sell. The fair value of collateral is determined based on appraisals. In some cases, adjustments were made to the appraised values due to various factors including age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in the collateral. When significant adjustments were based on unobservable inputs, the resulting fair value measurement has been categorized as a Level 3 measurement. Impaired loans with a carrying amount of $467 and $541 have a valuation allowance of $77 and $136 included in the allowance for loan losses as of September 30, 2015 and 2014 , respectively. Foreclosed real estate : The Company does not record foreclosed real estate owned at a fair value on a recurring basis. The fair value of foreclosed real estate was determined using Level 3 inputs based on appraisals or broker pricing opinions. In some cases, adjustments were made to these values due to various factors including the age of the appraisal, age of comparables included in the appraisal, and known changes in the market and in collateral. Foreclosed real estate is measured at fair value less estimated costs to sell at the date of foreclosure. Subsequent to foreclosure, additional writedowns may be recorded based on changes to the fair value of the assets. Mortgage servicing rights : Mortgage servicing rights (MSRs) do not trade in an active, open market with readily observable prices. While sales of MSRs do occur, the precise terms and conditions typically are not readily available. Accordingly, the Company estimates the fair value of MSRs using discounted cash flow models incorporating numerous assumptions from the perspective of market participants including servicing income, servicing costs, market discount rates, prepayments speeds, and default rates. Due to the nature of the valuation inputs, MSRs are classified within Level 3 of the valuation hierarchy. As of September 30, 2015 , mortgage servicing rights with a carrying amount of $1,315 have a valuation allowance of $105 to reflect their fair value of $1,210 . As of September 30, 2014 , mortgage servicing rights with a carrying amount of $1,784 have a valuation allowance of $160 to reflect their fair value of $1,624 . Real estate held for sale: The Company does not record real estate held for sale at a fair value on a recurring basis. The fair value of real estate held for sale was determined using Level 3 inputs based on appraisals or broker pricing opinions. In some cases, adjustments were made to these values due to various factors including the age of the appraisal, age of comparables included in the appraisal, and known changes in the market. Real estate held for sale is measured at fair value less estimated costs to sell at the time of transfer. Subsequent to transfer, additional writedowns may be recorded based on changes to the fair value of the assets.

In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Certain financial instruments with a fair value that is not practicable to estimate and all non-financial instruments are excluded from the disclosure requirements. Accordingly, the aggregate fair value amounts presented do not necessarily represent the underlying value of the Company for assets and liabilities not previously described. The Company, in estimating its fair value disclosures for financial instruments not described above, used the following methods and assumptions: Cash and cash equivalents : The carrying amounts of cash and cash equivalents reported in the consolidated balance sheets approximate those assets’ fair values. Securities held to maturity: The fair values of securities held to maturity are based on quoted market prices for similar securities, adjusted for differences in security characteristics. Loans: For variable-rate mortgage loans that re-price frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for fixed rate residential mortgage loans are based on quoted market prices for similar loans sold in conjunction with sale transactions, adjusted for differences in loan characteristics. The fair values for commercial real estate loans, rental property mortgage loans, and consumer and other loans are estimated using discounted cash flow analyses and using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Loans held for sale: Fair value of loans held for sale are based on commitments on hand from investors or prevailing market prices. Federal Home Loan Bank stock: The carrying amount of FHLB stock approximates its fair value based on the redemption provisions of the FHLB. Accrued interest receivable and payable: The carrying amounts of accrued interest receivable and payable approximate their fair values. Deposits: The fair value disclosed for interest-bearing and non-interest-bearing checking accounts, savings accounts, and money market accounts are equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The fair values of fixed rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities of the outstanding certificates of deposit. Advances from the Federal Home Loan Bank and notes payable: The fair values of FHLB advances and notes payable are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Advance payments by borrowers for property taxes and insurance: The carrying amounts of the advance payments by borrowers for property taxes and insurance approximate their fair values. Mortgage banking derivatives: The fair value of commitments to originate mortgage loans held for sale is estimated by comparing the Company’s cost to acquire mortgages and the current price for similar mortgage loans, taking into account the terms of the commitments and the credit worthiness of the counterparties. The fair value of forward commitments to sell residential mortgage loans is the estimated amount that the Bank would receive or pay to terminate the forward delivery contract at the reporting date based on market prices for similar financial instruments. The fair value of these derivative financial instruments was not material at September 30, 2015 or 2014 . The estimated fair values and related carrying amounts of the Company’s financial instruments are as follows: September 30, 2015 Quoted Prices in Active Markets for Significant Other Significant Other Carrying Estimated Fair Identical Assets Observable Inputs Unobservable Inputs Amount Value (Level 1) (Level 2) (Level 3) (In thousands) Financial assets: Cash and cash equivalents $ 16,488 $ 16,488 $ 16,488 — — Securities available for sale 80,286 80,286 — 80,286 — Securities held to maturity 2,459 2,490 — 2,490 — Loans, net 493,425 493,480 — — 493,480 Loans held for sale, net 431 431 — 431 — Federal Home Loan Bank stock 3,350 3,350 — — 3,350 Mortgage servicing rights 1,210 1,210 — — 1,210 Accrued interest receivable 1,965 1,965 1,965 — — Derivative asset 110 110 — 110 — Financial liabilities: Deposits 531,020 508,339 101,486 — 406,853 Advances from Federal Home Loan Bank 18,000 18,000 — 18,000 — Advance payments by borrowers for property taxes and insurance 5,382 5,382 5,382 — — Accrued interest payable 5 5 5 — — Derivative liability 110 110 — 110 — September 30, 2014 Quoted Prices in Active Markets for Significant Other Significant Other Carrying Estimated Fair Identical Assets Observable Inputs Unobservable Inputs Amount Value (Level 1) (Level 2) (Level 3) (In thousands) Financial assets: Cash and cash equivalents $ 17,608 $ 17,608 $ 17,608 — — Securities available for sale 90,346 90,346 — 90,346 — Loans, net 416,874 415,857 — — 415,857 Loans held for sale, net 326 326 — 326 — Federal Home Loan Bank stock 2,670 2,670 — — 2,670 Mortgage servicing rights 1,624 1,624 — — 1,624 Accrued interest receivable 1,784 1,784 1,784 — — Derivative asset 87 87 — 87 — Financial liabilities: Deposits 454,928 442,342 77,790 — 364,552 Advances from Federal Home Loan Bank 17,000 17,000 — 17,000 — Advance payments by borrowers for property taxes and insurance 5,869 5,869 5,869 — — Accrued interest payable 3 3 3 — — Derivative liability 87 87 — 87 —

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share Earnings per common share is computed using the two-class method. Basic earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding, adjusted for weighted average unallocated ESOP shares, during the applicable period, excluding outstanding participating securities. Participating securities include non-vested restricted stock awards and restricted stock units, though no actual shares of common stock related to restricted stock units are issued until the settlement of such units, to the extent holders of these securities receive non-forfeitable dividends or dividend equivalents at the same rate as holders of the Company's common stock. Diluted earnings per share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation using the treasury stock method. The following table presents a reconciliation of the number of shares used in the calculation of basic and diluted earnings (loss) per common share (in thousands, except share and per share data). Years Ended September 30, 2015 2014 (Dollars in thousands) Net income (loss) $ 3,524 $ (1,435 ) Basic potential common shares: Weighted average shares outstanding 4,493,441 5,087,676 Weighted average unallocated Employee Stock Ownership Plan shares (365,976 ) (386,834 ) Basic weighted average shares outstanding 4,127,465 4,700,842 Dilutive effect of equity awards 1,133 1,364 Diluted weighted average shares outstanding 4,128,598 4,702,206 Basic earnings per share $ 0.85 $ (0.31 ) Diluted earnings per share $ 0.85 $ (0.31 )

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and principles of consolidation	Organization and principles of consolidation: The consolidated financial statements include the accounts of the Company and the Bank. The financial statements of the Bank include the accounts of its wholly-owned subsidiary, CRH, Inc., a Wisconsin real estate holding company. The financial statements of the Bank also include one wholly-owned limited liability corporation (LLC) formed to own certain of the Bank’s foreclosed properties. All significant intercompany balances and transactions have been eliminated in consolidation.
Jumpstart Our Business Startups Act	Jumpstart Our Business Startups Act: The Jumpstart Our Business Startups Act (the JOBS Act), which was signed into law on April 5, 2012, has made numerous changes to the federal securities laws to facilitate access to capital markets. Under the JOBS Act, a company with total annual gross revenues of less than $1.0 billion during its most recently completed fiscal year qualifies as an “emerging growth company.” The Company qualifies as an “emerging growth company” and believes that it will continue to qualify as an “emerging growth company” until five years from the completion of the stock offering, which occurred on April 9, 2013. As an “emerging growth company,” the Company has elected to use the extended transition period to delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. Accordingly, the financial statements may not be comparable to the financial statements of companies that comply with such new or revised accounting standards.
Use of estimates	Use of estimates: In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP), management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, valuation of deferred tax assets and valuation of mortgage servicing rights.
Cash and cash equivalents	Cash and cash equivalents: For purposes of the consolidated statements of cash flows, cash and cash equivalents includes cash, due from banks, and interest-bearing deposits. The Company maintains amounts due from banks that, at times, may exceed federally insured limits. Management monitors these correspondent relationships and has experienced no losses. Accordingly, in the opinion of management, no material risk of loss exists.
Securities	Securities: Unless classified as "held-to-maturity", all securities are classified as “available-for-sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported in accumulated other comprehensive income, net of the related deferred tax effect. Securities are classified as "held-to-maturity" and recorded at amortized cost when management has the ability and intent to hold the securities to maturity. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Declines in the fair value of individual available-for-sale securities below their amortized cost basis that are deemed to be other-than-temporary impairment losses are reflected as realized losses. In determining whether an other-than-temporary impairment exists, management considers many factors including (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent or requirement of the Company to sell its investment in the issuer prior to any anticipated recovery in fair value. If the Company intends to sell an impaired security, it records an other-than-temporary loss in an amount equal to the entire difference between the fair value and amortized cost of the security. If a security is determined to be other-than-temporarily impaired, but the Company does not intend to sell the security, only the credit portion of the estimated loss is recognized in earnings, with the other portion of the loss recognized in other comprehensive income. The credit loss component recognized in earnings is identified as the amount of principal cash flows not expected to be received over the remaining term of the security as estimated based on cash flow projections discounted at the applicable original yield of the security. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
Loans held for sale	Loans held for sale: Loans held for sale are recorded at the lower of cost or fair value as determined on an aggregate basis. Fees received from the borrower and the direct costs of loan originations are deferred and recorded as an adjustment to the sales price, when such loans are sold.
Loans	Loans: The Company grants commercial, mortgage and consumer loans to customers principally located in Southeastern Wisconsin. The ability of the Company’s loan customers to meet the terms of their loans is dependent upon the general economic conditions in this area and real estate values. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are generally reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, and deferred loan fees or costs on an originated basis. Interest income is accrued on the unpaid principal balance. Loan origination and commitment fees and certain direct loan origination costs on loans receivable are deferred, and the net amounts amortized as an adjustment of the related loan’s yield. These amounts are amortized, using the level-yield method, over the contractual life of the related loans. Unamortized deferred amounts are included in interest income upon repayment or sale of the related loan. The accrual of interest on loans is discontinued at the time the loan is ninety days delinquent, unless the loan is well-secured and in the process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual status or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual status or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for loan losses	Allowance for loan losses: For all portfolio segments, the allowance for loan losses is maintained at the level considered adequate by management of the Company to provide for losses that are probable. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. In determining the adequacy of the allowance balance, the Company makes continuous evaluations of the loan portfolio and related off-balance sheet commitments, considers current economic conditions and historical loss experience, and reviews specific problem loans and other factors. When establishing the allowance for loan losses, management categorizes loans into risk categories generally based on the nature of the collateral and the basis of repayment. These risk categories and their relevant risk characteristics are as follows: Single family: Single family loans are real estate loans generally smaller in size and are homogeneous because they exhibit similar characteristics. Single family loans are underwritten by evaluating the credit history of the borrower, the ability of the borrower to meet the debt service requirements of the loan and total debt obligations, as well as the underlying collateral and the loan to collateral value. Also included in this category are junior liens on 1-4 family residential properties. These loans consist of closed-end loans secured by junior liens on 1-4 family residential properties. Underwriting standards for single family loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements. Construction and land development: These loans are secured by vacant land and/or property that are in the process of improvement, including (a) land development preparatory to erecting vertical improvements or (b) the on-site construction of industrial, commercial, residential, or farm buildings. Repayment of these loans can be dependent on the sale of the property to third parties or the successful completion of the improvements by the builder for the end user. For purposes of this classification, “construction” includes not only construction of new structures, but any loans originated to finance additions or alterations to existing structures and the demolition of existing structures to make way for new structures. Until a permanent loan originates, or payoff occurs, all construction loans secured by real estate are reported in this loan pool. Loans to finance construction and land development that are not secured by real estate are segmented and reported separate from this pool. In the event a loan is made on property that is not yet improved for the planned development, there is the risk that necessary approvals will not be granted or will be delayed. Construction loans also run the risk that improvements will not be completed on time or in accordance with specifications and projected costs. Commercial business: Commercial business loans are extended primarily to middle market customers. Such credits typically comprise working capital loans, loans for physical asset expansion, asset acquisition loans and other business loans. Loans to closely held businesses will generally be guaranteed in full or for a meaningful amount by the owners of the business. Commercial business loans are made based primarily on the historical and projected cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not behave as forecasted and collateral securing loans may fluctuate in value due to economic or individual performance factors. Minimum standards and underwriting guidelines have been established for all commercial and industrial loan types. Multifamily: Multifamily loans include loans to finance non-farm properties with five or more units in structures primarily to accommodate households on a temporary or permanent basis. Such credits are typically originated to finance the acquisition of an apartment or condo building/complex. Multifamily loans are made based primarily on the historical and projected cash flow of the subject multifamily property, with assumptions made for vacancy rates. Cash flows and ultimate loan performance rely on the receipt of rental income from the tenants of the property who are themselves subject to fluctuations in national and local economic and unemployment trends. Commercial real estate: These loans are primarily secured by office and industrial buildings, warehouses, small retail shopping facilities and various special purpose properties, including hotels and restaurants. These loans are subject to underwriting standards and processes similar to commercial business loans. These loans are viewed primarily as cash flow loans and the repayment of these loans is largely dependent on the successful operation of the property. Loan performance may be adversely affected by factors impacting the general economy or conditions specific to the real estate market such as geographic location and/or property type. Consumer and other: These loans may take the form of installment loans, demand loans, or single payment loans, and are extended to individuals for household, family, and other personal expenditures. These include direct consumer automobile loans extended by the Company for the purpose of purchasing a new or used vehicle for personal use. Consumer and installment loans are underwritten by evaluating the credit history of the borrower and the ability of the borrower to meet the debt service requirements of the loan and total debt obligations. Also included in this category are home equity lines of credit. These loans consist of revolving open-end lines of credit secured by 1-4 family residential properties extended to individuals for household, family or other personal expenditures. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which include, but are not limited to, loan-to-value and affordability ratios, risk-based pricing strategies, and documentation requirements. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. In addition, regulatory agencies, as an integral part of their examination processes, periodically review the Company’s allowance for loan losses, and may require the Company to recognize adjustments to its allowance based on their judgments of information available to them at the time of their examinations. The allowance consists of specific and general components. The specific component relates to loans that are classified as impaired, and an allowance is established when the collateral value, discounted cash flows or observable market price of the impaired loan are lower than the carrying value of that loan. The general component covers non-impaired loans and is based on the Company’s own loss experience over the most recent seventeen quarters, adjusted for qualitative factors. These qualitative factors consider local economic trends, concentrations, management experience and other elements of the Company’s lending operations. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining the impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the fair value of collateral, if the loan is collateral dependent, the present value of expected future cash flows discounted at the loan’s effective interest rate, or the loan’s obtainable market price. Single family and consumer and other loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual homogeneous loans for impairment disclosures, unless such loans are the subject of a restructuring agreement due to the financial difficulties of the borrower, the loans are related with another commercial type loan or the loans experience significant payment delinquencies and are not insured.
Troubled debt restructurings	Troubled debt restructurings: Loans are accounted for as troubled debt restructurings when a borrower is experiencing financial difficulties that lead to a restructuring of the loan, and the Company grants a “concession” to the borrower that they would not otherwise consider. These concessions include a modification of terms such as a reduction of the stated interest rate or loan balance, a reduction of accrued interest, an extension of the maturity date at an interest rate lower than a current market rate for a new loan with similar risk, or some combination thereof to facilitate repayment. Troubled debt restructurings are classified as impaired loans. Payment performance prior and subsequent to the restructuring is taken into account in assessing whether it is likely that the borrower can meet the new terms. A period of sustained repayment, for at least six months, is generally required for return to accrual status. This may result in the loan being returned to accrual at the time of restructuring. A loan that is modified at a market rate of interest will not be classified as a troubled debt restructuring or impaired in the calendar year subsequent to the restructuring if it is in compliance with the modified terms.
Federal Home Loan Bank stock	Federal Home Loan Bank stock: Federal Home Loan Bank (FHLB) stock consists of the Company’s required investment in the capital stock of the FHLB. No ready market exists for these securities and they have no quoted market value; as such the stock is carried at cost. Management reviews for impairment based on the ultimate recoverability of the cost basis in the FHLB stock, and no impairment has been identified as a result of these reviews.
Foreclosed real estate	Foreclosed real estate: Real estate acquired by foreclosure or by deed in lieu of foreclosure is initially recorded at fair value less cost to sell at the date of foreclosure, establishing a new cost basis. Costs relating to the development and improvement of property are capitalized; holding costs are charged to expense. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of their carrying amount or fair value less cost to sell. Revenues and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed real estate.
Real estate held for investment/sale	Real estate held for investment/sale: Real estate held for investment consists of rental properties. Rental properties are carried at the lower of cost less provisions for depreciation computed by the straight-line method over the estimated life of the property. Rental revenue is recognized on a straight-line basis over the term of the lease unless another systemic and rational basis is more representative of the time pattern in which the use benefit is derived from the leased property, or fair value less costs to sell. The difference between rental income earned on a straight-line basis and the cash rent due under provisions of the lease agreements is recorded as deferred rent receivable and is included as a component of other assets in the accompanying consolidated balance sheets. A property is considered held for sale when a contract for sale is entered into or when management has committed to a plan to sell an asset, the asset is actively marketed, and sale is expected to occur within one year. Property reported as held for sale is reported at the lower of the carrying amount or fair value less costs to sell and is not depreciated. The Company evaluates the carrying value of all real estate held when an indicator of impairment is deemed to exist. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount which the carrying amount of the asset exceeds the fair value of the asset.
Office properties and equipment	Office properties and equipment: Office properties including equipment are stated at cost less accumulated depreciation, and include expenditures for new facilities and items that substantially increase the useful lives of existing buildings and equipment. Expenditures for normal repairs and maintenance are charged to expense as incurred. When properties are retired or otherwise disposed of, the related cost and accumulated depreciation are removed from the respective accounts and the resulting gain or loss is recorded.
Mortgage servicing rights and Transfers of financial assets	Mortgage servicing rights: Mortgage servicing rights (MSRs) are initially recognized at fair value when loans have been sold to investors and are amortized over the lives of the loans. Upon sale of loans with servicing retained, the servicing rights are recorded at fair value and remaining proceeds received are allocated to the loan. Amortization of MSRs is based on the ratio of net servicing income received in the current period, to total remaining net servicing income projected to be realized from the MSRs. MSRs are periodically assessed for impairment, which is calculated using estimated net cash flow analysis on a discounted basis. Impairment is recognized in the statement of income, during the period in which it occurs, as an adjustment to the corresponding valuation allowance. For purposes of performing an impairment evaluation, the serviced loan portfolio is stratified on the basis of certain risk characteristics including loan type (i.e., fixed or adjustable interest rates). Transfers of financial assets: Transfers of financial assets are accounted for as sales only when the control over the financial assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Employee stock ownership plan	Employee stock ownership plan: The Company has an employee stock ownership plan (ESOP) covering substantially all employees. The cost of shares issued to the ESOP but not yet allocated to participants is presented in the consolidated balance sheets as a reduction of stockholders' equity. Compensation expense is recorded based on the market price of the shares as they are committed to be released for allocation to participant accounts.
Stock-based compensation	Stock-based compensation: The Company accounts for its equity awards in accordance with ASC Topic 718. ASC Topic 718 requires public companies to recognize compensation expense related to stock-based equity awards in their income statements. See Note 14 below for more information.
Income taxes	Income taxes: The Company, the Bank, and its subsidiaries file consolidated federal income tax returns and combined state income tax returns. Accordingly, amounts equal to tax benefits of those companies having taxable federal losses or credits are reimbursed by the other companies that incur tax liabilities. Deferred income taxes are provided using the liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of the changes in tax laws and rates as of the date of enactment. The Company accounts for uncertainty in income taxes to determine whether tax benefits claimed or expected to be claimed on a tax return, should be recorded in the consolidated financial statements. The Company may recognize the tax benefit for an uncertain tax position if it is more-likely-than-not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being utilized upon ultimate settlement. It is the Company’s policy that interest and penalties associated with unrecognized tax benefits are classified as additional income taxes in the statement of operations.
Derivative financial instruments and hedging activities	Derivative financial instruments and hedging activities: All derivatives are recognized in the consolidated balance sheets at their fair value. Derivative contracts are maintained related to commitments to fund residential mortgages (interest rate locks) in connection with residential mortgages intended for sale. Such commitments are recorded at fair value in other assets or liabilities, with changes in fair value recorded in net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements, and for fixed rate commitments, also considers the committed rates and current levels of interest rates. Derivative contracts are also maintained related to certificates of deposit, for which changes in the fair value of the derivative are recorded in earnings.
Comprehensive income	Comprehensive income: Comprehensive income consists of net income and other comprehensive income. Other comprehensive income includes unrealized gains and losses on securities available-for-sale, which are also recognized as separate components of equity.
Reclassification	Reclassification: Certain amounts in the 2014 consolidated financial statements have been reclassified to conform to the 2015 presentation. These reclassifications had no effect on net income or loss.
Segment reporting	Segment reporting: The Company views the Bank as one operating segment, therefore, separate reporting of financial segment information is not considered necessary. The Company approaches the Bank and its other subsidiaries as one business enterprise, which operates in a single economic environment, since the products and services, types of customers and regulatory environment all have similar characteristics.
Recent accounting pronouncements	Recent accounting pronouncements: In January 2014, the FASB issued ASU 2014-04, Receivables (Topic 310) - Troubled Debt Restructurings by Creditors. ASU 2014-04 is intended to reduce diversity by clarifying when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU 2014-04 is effective for annual periods beginning after December 15, 2014, and interim periods within annual periods beginning after December 15, 2015. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). ASU 2014-09 is intended to clarify the principles for recognizing revenue and to develop a common revenue standard for U.S. GAAP. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2018 and interim periods within annual periods beginning after December 15, 2019. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures. In June 2014, the FASB issued ASU 2014-11, Transfers and Servicing (Topic 860) - Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures. ASU 2014-11 is intended to clarify the accounting for and improve the disclosures related to repurchase-to-maturity transactions and repurchase financings. ASU 2014-11 is effective for annual periods beginning after December 15, 2014 and interim periods within annual periods beginning after December 15, 2015. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures. In June 2014, the FASB issued ASU 2014-12, Compensation - Stock Compensation (Topic 718) - Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved After the Requisite Service Period. ASU 2014-12 is intended to clarify the accounting for the timing of expense recognition related to employee share-based payments in which a performance target that effects vesting could be achieved after the requisite service period. ASU 2014-12 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures. In August 2014, the FASB issued ASU 2014-14, Receivables - Troubled Debt Restructuring by Creditors (Topic 310) - Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure. ASU 2014-14 is intended to clarify the accounting for and improve the consistency of balance sheet classification of certain foreclosed mortgage loans that are either fully or partially guaranteed under government programs. Greater consistency in classification of such mortgage loans upon foreclosure is expected to provide more decision-useful information about a creditor's foreclosed mortgage loans that are expected to be recovered, at least in part, through government guarantees. ASU 2014-14 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Adoption by the Company is not expected to have a material impact on the consolidated financial statements and related disclosures.
